To determine the amount oflead that leaches from soil tinder the simulated conditions ofgastric digestion. Special Safety Handling Procedures: Use respirator when handling lead-contaminated soil. Disposal ofWaste Materials: Must be in compliance with the procedures outlined in the Stine-Haskell Chemical Hygiene Plan. SOP Number to be followed: BTOO1 -T-001 Variant from the SOP for this test: The lead analyis Will be performed at: Conoco Inc. 1000 S. Pine Rd. R& E West Dock, Ponca City, OK, 74602-1267 Attn.
